Her fiancé, a marine held captive for months in a war-torn country, is back on American soil…with secrets.

For six agonizing months, Sidney Parker had no idea if her beloved fiancé, a US Marines captain, was alive or dead. Held captive in a South American dictatorship, Nick Corelli is suddenly back home in Texas. But instead of the romantic reunion Sidney expects, Nick is working with the CIA—and another mysterious agency—on a covert mission. One that places Sidney's life in jeopardy. When the safe house meant to protect them is compromised, Nick rushes Sidney to a mountain retreat…and now she wants answers. Yet their greatest enemy is lying in wait for the ultimate showdown.
